Hyundai Ioniq 5 N NE N
Weaknesses, engine ratings and buying advice
The Ioniq 5 N — when a motorsport department gets unlimited budget. Ioniq5N-DM dual motors, 641 hp in N Grin Boost, 0–60 in 3.4 seconds. 84 kWh battery thermally conditioned for track days. N e-shift simulates gear changes. Dual-motor torque vectoring outperforms any mechanical LSD at this price.
Issues: Post-track battery temps prevent immediate fast charging. Tire wear is considerable. Real-world range ~220 miles.
Test-drive checklist: Test N Grin Boost (10-second window). Check battery temp after drive.
2026 market: New at ~$75,900. Used stock minimal, from ~$68,000.
Insider pick: Only buy if the track is actually in the plans — cheaper 3.4-second alternatives exist for highway use.
Engine Overview
The Hyundai Ioniq 5 N NE N is available with one engine variant at 609 hp.
Hyundai's first performance EV carries i30 N spirit into a 2,200-kg body — and pulls it off more convincingly than physics would suggest. The N e-Shift fake DCT gives zero lap-time benefit and genuine emotional benefit. On track, expect ~25 km of hard running before thermal throttling. Pirelli P Zero Corsa tires can show 1mm tread at 7,000 km. The E-GMP platform's ICCU failure (2–10% of owners) applies — verify recall status.
- !! ICCU module failure — 12V battery not charging from 20,000 km
E-GMP platform issue: MOSFET in ICCU (Integrated Charging Control Unit) fails, 12V battery stops charging. Ioniq 5 N uses a different ICCU than standard Ioniq 5. Stranding risk.
Symptoms: 12V battery warning; vehicle won't start; stranding; check electrical system message. - !! High-voltage battery module failure — charging limited from 30,000 km
Cell voltage deviation between modules triggers BMS fault. Charging limited to 73-80%, vehicle enters reduced power mode. Complete battery replacement needed under warranty.
Symptoms: BMS malfunction warning on display; charging stops at 73-80%; reduced power; workshop visit required. - !! Recall: Brake software fault in LFB mode
NHTSA recall 25V235: Two software defects in 2025 Ioniq 5 N — Left-Foot Braking (LFB) can trigger ABS depressurization, N e-Shift VCU causes momentary continued acceleration after pedal release. 1,508 vehicles affected. OTA update available.
Symptoms: Reduced braking in LFB mode; momentary continued acceleration after throttle release in e-Shift mode.
Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| ICCU Failure — Charging Unit Dies Without Warning The E-GMP platform ICCU fails when internal SiC MOSFET is damaged by voltage spikes, blowing the 130A fuse and killing 12V charging. Consumer Reports: 2–10% failure rate across E-GMP vehicles. Symptoms: Loud pop from rear, 'Check EV System' warning, fails to charge at any station, 12V battery dies from 30,000 km | High | |
| Software Recall: LFB/N e-Shift Causes Longer Stops and Unintended Acceleration IEB software depressurizes ABS with Left-Foot Braking active. Follow-up fix caused unintended acceleration for up to 2.5 seconds in N e-Shift mode. 1,508 vehicles affected. Symptoms: Longer braking distances in LFB mode; after update: car accelerates for up to 2.5s after throttle release | Low | |
| HV Battery Failure — Cell Voltage Deviation P1AA700 BMS detects >180 mV cell voltage deviation. Charging stops at 55–62% SOC, DC fast charging impossible. Only fix: full battery pack replacement. Lemon-law buybacks documented under 5,000 miles. Symptoms: 'Check Electric Vehicle System' warning, charging stops at 55–62%, no DC fast charging possible from 15,000 km | High | |
| AC Charge Port Overheats at 48A — Cuts Out After 30 Minutes Level 2 charging at 48A overheats the port to 99°C within 30–38 minutes, cutting the session. Doesn't auto-restart. Affects all E-GMP vehicles. Class action filed in California. Symptoms: Charging stops after 30–38 minutes, warning displayed, port won't auto-restart | Low | |
| 12V Battery Drains from Bluelink App Polling Bluelink app polls up to 5,000 requests/day, draining 12V battery in 2–3 days. Hyundai capped server to 20 transactions/day. Repeated failures on individual vehicles documented. Symptoms: Car won't start despite full HV battery, 'battery low' alert, all systems dead from 25,000 km | Low | |
| Power Throttling After ~25 km of Full Throttle on Track After ~6 laps / 25 km flat-out, battery throttles power. Tire grip degrades simultaneously. Brake pedal feel loses confidence. Recovery: ~18 min charging + cooling. Two Nürburgring laps nearly empties the battery. Symptoms: Noticeable power drop, reduced acceleration, battery warning | Low |
